The red grape variety comes from France. Synonyms are Cabernet Duras, Durade, Duras, Durasca, Duras Femelle, Duras Male, Duras Rouge and Durazé. The name is derived from "dur" (hard) and refers to the hard wood of the vine. It should not be confused with the Italian variety Ner d'Ala (Dúras). According to an unverifiable hypothesis, it is said to be a descendant of the ancient grape variety Duracina mentioned by Cato (234-149 BC) and Columella (1st century AD). It was first reliably mentioned in 1842 in Gaillac in southwest France. According to DNA analyses carried out in 2013, it comes from a presumably natural cross between Tressot Noir x Savagnin Blanc(Traminer). However, this is based on only 20 DNA markers (see molecular genetics). Previously it had been considered the parent of Tressot Noir.
The medium ripening vine is susceptible to black spot disease, powdery mildew and eutypiosis. It produces full-bodied and alcoholic, dark red wines with strong acidity and peppery notes. The variety is grown in the Tarn department. In 2010, 892 hectares of vineyard area were designated with a downward trend.
